Mount Fitz Roy (Cerro Fitz Roy)

EXPERT // HAZARD
Full Route Report

The trek to Laguna de los Tres is one of the primary day activities in Los Glaciares National Park, providing a close-perspective view of the granite massif of Mount Fitz Roy (3,405m). The route follows an out-and-back trail through mixed forest and glaciated valleys, passing the Piedras Blancas viewpoint before the final ascent. The journey is defined by a significant transition from the low-lying valley floor to the high-alpine environment of the lagoon, which sits directly below the main peaks.

Tregennis Coastal Walk

MODERATE // CHLG
Full Route Report

The Tregennis Peninsula offers some of the wildest and oldest coastal scenery in Wales. This stunning 6-mile (9.6km) circular walk starts from the tiny, fjord-like harbor of Porth Clais, just down the road from the city of St Davids. It traces the jagged perimeter of the peninsula along the Pembrokeshire Coast Path, gazing out over the ferocious tidal races of the Ramsey Sound towards Ramsey Island. The geology here is incredibly ancient (Precambrian volcanic rock), creating sharp, jagged headlands. The walk passes active sea-cliff farms, deep hidden 'geo's (inlets), the historic St Justinian's lifeboat station, and the dramatic ruins of a medieval copper mine right on the cliff edge.

The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.

Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.

Full Scale Documentation
Route A // Hazard Verdict
Mount Fitz Roy (Cerro Fitz Roy)
EXPERT // HAZARD
high wind exposure: Strong winds are common in the Fitz Roy massif, particularly in the afternoon. Gusts can make the final ascent unstable in exposed conditions.
lower limb strain: The final descent is steep and rocky, which can strain knees and ankles on the return journey.
Route B // Hazard Verdict
Tregennis Coastal Walk
MODERATE // CHLG
unguarded gales: Tregennis faces straight into the Atlantic and Irish Sea. In poor weather, the wind on the high cliffs can be strong enough to pose a literal blow-over risk.
cliff edge erosion: The path is rugged and runs very close to the sheer drops, particularly around the ruined copper mine at St Elvis.
